Firefox icon remains in the Dock after I quit the application (CMD-Q and File > Quit alike).

I have unchecked "Show recent apps in Dock" in System Preferences > Dock & Menu Bar.

Is there a way to fix/prevent this?

  • With Firefox closed, remove the icon from the Dock, right-click > Options > Remove from Dock or click-hold and drag it off, and it shouldn't stay the next time you quit Firefox Sep 18, 2021 at 16:22
  • Thanks. I tried this but FF was in the dock again after restarting and quitting. I tried unchecking "keep in dock" while FF was still running and that seems to have done the trick. I saw your edits by the way, will make sure to get the capitals right next time.

  • nope, it's back in the Dock again. I'm going to try and find out whether CleanMyMac has anything to do with it....

Right click the icon in the Dock > Options

If it's running you'll see "Keep in Dock" which you need to uncheck
if it's not running, instead you'll see "Remove from Dock"

Both do the same thing, remove it from the Dock when it's not running.

The third method is to grab the icon in the Dock & drag it out into an empty area of your desktop, then release…

    Thanks. I tried "remove from dock" numerous times but no dice. After reading your answer I tried unchecking "keep in dock" while FF was still running and that seems to have done the trick.

  • Note that if you move the icon while the application is running, it will turn that back on and start keeping the icon in the dock again. Sep 18, 2021 at 16:56
  • ....and it's back again. I run CleanMyMac every now and then, could that be causing the problem? I'll try and find out, will report back
